On Tuesday, Apple released an update for its Apple TV (2nd gen) that addresses the widespread complaints of video flickering common when the set top box is used on older model high-definition televisions. Last week, Apple said it was actively working on a fix and assured afflicted Apple TV users that a software update to remedy the problem would be coming soon.

If you haven't already grabbed it, the Apple TV Software Update (4.2.1) is available now for download directly from the second-generation Apple TV. According to Apple's formal announcement of the update's availability, the software tweak addresses:

TV compatibility: Addresses issues that may cause the screen to flicker or display incorrect color on some older TVs.

Wake from sleep: Addresses an issue where Apple TV may not wake from sleep.

Audio: Addresses an issue where audio may not be heard on some TV models after switching from another input.

The so-called flickering epidemic was first reported the day of Apple's February release of Apple TV 4.2, which also brought with it support for AirPlay in third-party applications, and as sports fan know, live streaming games from NBA League Pass and MLB.TV.
